It comes as police continue to piece together how the deadly crash unfolded.

It’s believed an Audi driver was trying to turn right at the intersection of Boronia Road and Amesbury Avenue when he spotted the motorcyclist in the distance, and thought he had plenty of room to turn.

"As he went to complete the manoeuvre, the motorcyclist came up on him so fast... the next thing you knew, the motorcyclist struck the vehicle,” Acting Detective Inspector Brad McArthur said yesterday.

"It struck with such force, it spun the Audi around 180 degrees."

The 50-year-old male driver of the Audi SUV, and his 47-year-old female passenger, both from Wantirna, were uninjured and stopped to assist.

A 32-year-old Boronia man, who was the driver and sole occupant of the Honda, was also uninjured and also stopped to help.

No charges are expected to be laid.

Act Det Insp McArthur said detectives will consider the lack of street lighting at the scene as a possible cause, but said the motorcyclist's actions were the main factor in the crash.

The 37-year-old was known to police, and was carrying a quantity of drugs and cash at the time of the collision.

"It’s driving behaviour that has caused this crash, not the road," he said.

"If people took the time to obey the law in regards to speed limits, we’d be a lot better off. The road toll would certainly be reduced."
